Abstract

본 발명은, 압축된 비디오 신호를 위한 알려진 트랜스코더는 데이터 신호가 전송된 사이에, 거기에 연결된 디코더와 코더를 구성한다.In the present invention, a known transcoder for a compressed video signal constitutes a decoder and coder connected thereto while the data signal is transmitted.

압축된 비디오 신호가 소위 차동화상과 상용화상이라는 것을 구성하고 있기 때문에 디코더와 코더 둘다 차동화상을 디코딩하고 코딩하는 것에 이용되고, 사용화상을 디코딩하고 코딩하는 것에 이용되지 않는 피드백루프를 가져야 했다. 예컨대, 코더의 피드백루프에서 예상수단(모션 보상과 모션 평가)을 존재시키기 위해 코더에서 많은 재산이 수행됐다. 요구된 계산은 본 발명에 따른 트랜스코더에서 데이터 신호에 더하여 하나 또는 그 이상 정보신호를 부수적으로 전송하는 것에 의해 현저하게 줄여지고, 완전한 디코딩과 완전한 코딩은 더 이상 생기지 않는다.Since the compressed video signal constitutes a so-called differential picture and a commercial picture, both the decoder and the coder had to have a feedback loop that is used to decode and code the differential picture and not to decode and code the used picture. For example, a lot of property has been done in the coder to present the means of prediction (motion compensation and motion evaluation) in the coder's feedback loop. The required calculation is significantly reduced by the additional transmission of one or more information signals in addition to the data signal in the transcoder according to the invention, and complete decoding and complete coding no longer occur.
